利用线程显示数据

[staticuser]

我在读取数据库的数据的时候，因为数据量不少，所以程序会有稍稍的卡死，然后一下子显示出来了，现在我想利用线程来控制数据的显示，就是读取到哪里就显示出多少，既有动态的效果，程序又不会卡死，请问这个如何实现啊。。。

将写数据的代码置于独立的线程中。

            Thread thread = new Thread(new ThreadStart(wrapper.DoMyThread));
            thread.Start(); 

            while (thread.IsAlive)
            {
                ;
            }

            Thread.CurrentThread.Join(100); 
            Console.WriteLine("主线程:我接着进行……"); 
            for (int i = 0; i < 10; i++)

        { 
            Console.WriteLine(data.ToString()); 
            Console.WriteLine("主线程:收到了子线程的通知！"); 
        } 
    }

上面的那个少发了,以这个为准吧,win32控制台程序
